System Of A Down Pledges Again

System Of A Down, already confirmed to headline this year's edition of Ozzfest, have also already confirmed that they will again headline this year's Pledge Of Allegiance tour, according to a spokesperson from Immortal Tour and Events, one of the tour's producers. A co-headliner has not yet been chosen, but the fall festival will again feature five acts. Last year, Slipknot, Rammstein, and Mudvayne played the full circuit, while No One and American Head Charge alternated opening duties.
